[jira] [Created] (MESOS-1280) Add replace task primitive

Niklas Quarfot Nielsen created MESOS-1280:
---------------------------------------------

             Summary: Add replace task primitive
                 Key: MESOS-1280
                 URL: https://issues.apache.org/jira/browse/MESOS-1280
             Project: Mesos
          Issue Type: Sub-task
            Reporter: Niklas Quarfot Nielsen


Also along the lines of MESOS-938, replaceTask would one of a couple of primitives needed to support various task replacement and scaling scenarios. This replaceTask() version is significantly simpler than the first proposed one; it's only responsibility is to run a new task info on a running tasks resources.
The running task will be killed as usual, but the newly freed resources will never be announced and the new task will run on them instead.
